Yellow Hornet
Known as 'ke-buchi-suzumebachi' in Japanese, a common hornet in Japan and Korea. Builds large paper nests in trees and under eaves. Less aggressive than the giant hornet but still capable of painful stings.
Did You Know?
This species is responsible for more wasp stings in Japan than any other species because it frequently builds nests near human habitations.
Stridulating Passalid
A large, shiny black bess beetle with prominently punctate-striate elytra and strong mandibles. It lives in family groups within decaying logs. Known for producing a wide repertoire of stridulatory sounds for communication.
Did You Know?
Adults produce sounds by rubbing specialized ridges on the abdomen against the underside of the wings, creating at least 14 distinct calls.
